定语从句中只用that的特殊情况小析
定语从句中只用 that的特殊情况小析摘要：近几年来，高考英语针对定语从句的知识点频繁出考题，其中以which和that的特殊情况最为常见。
本文就定语从句中that的几种特殊用法作出讲解，希望同学们能掌握并学会巧妙运用。
关键字：高考；定语从句；特殊用法一、那些只能用that引导的定语从句1.当先行词是不定代词时英语中有一类代词，它们没有明确的指代对象，只表达一个模糊的概念，于是我们把它们叫做不定代词，如all, much, little, something, everything anything, nothing, none, the one等等，这样的情况下，其后的定语从句的引导词只能用that。
那么，这是什么原因呢？这要从that和which本身的概念上说起，我们最初接触这两个单词的时候，参考翻译得知，that是“那一个”，而which是“哪一个”，由此，我们是不是可以这样说，which表示哪一个的话，本身是具有选择倾向的，而that表示那一个，本身就是具有特定指代倾向的。
在明白这两个概念之后，再回过头去看不定代词做先行词，它们都是没有特定指代的，也就不具备可选择性，比如all，翻译为“所有”，既然都是所有了，那就完全不用选择了；再比如everything，翻译为“每一件事”或者“每一样东西”，同样也具有全指代的特性，因此也不用选择；最后，看到none，翻译为“一个都没有”，既然都没有了，我们还选什么呢？因此，在这样的不定代词作为先行词，本身就没有特定指代的情况下，我们只用that，不用which。
例：Do you have anything that you want to say for yourself?This is all that I have done for him.1.当先行词被only/any/few/little/no/all/very等词修饰时带着方才的概念，我们再来看看这种情况，其中的any、few、little、no、all都属于不定代词类，不论它们是自己做先行词，还是去修饰先行词，都统一依照之前的概念，使用that引导定语从句。
